"Process server Leslie V. Kinsey wrote that Kepner’s SUV sat running in the driveway and the lights inside the Titusville home were on, but no one responded to repeated knocks or the doorbell.
Kinsey said a "No Trespassing" sign was posted on the property and a Ring doorbell camera was visible near the entrance. She announced several times that she was there to serve a subpoena and left the paperwork on the SUV’s windshield at 10:29 a.m.
When Kinsey returned, the SUV had left and the
subpoena he placed on its windshield was gone."
Don't you have to serve someone person to person? Can you just leave it on a windshield now?
